Dangerously hot weather will expand across much of the central United States this weekend and into next week, pushing temperatures above 100 degrees Fahrenheit (37.8 degrees Celsius) from Dallas to North Dakota with roughly 70 million people facing heat advisories.
A heat dome, where atmospheric conditions trap heat, will create sustained high temperatures and accumulating discomfort. Overnight low temperatures aren’t expected to come down enough for people to have much chance to recover, allowing heat stress to build as the bad weather lingers, forecasters said. The high humidity will make it feel even worse.
